13 Claims.

My invention relates to a brake hanger bracket for a railway car andmore particularly to a novel arrangement for retaining a hanger in abrake hanger bracket and securing it against 5 Vibration.

It is a Well known fact that wear on brake hangers and on the jaws ofbrake hanger brackets is principally due to vibration and not due to thenormal wear which occurs between parts.

10 Because of this fact many designs of wear plates for brake hangerbrackets have been evolved and numerous arrangements for securing thehangers within the brackets have also been devised. The

object of my invention is to provide a novel ar- 15 rangement which willclose the brake hanger jaw and provide a substantial amount of Wearmetal beneath the top member of the hanger while at the same timeproviding that'such wear will not result in chattering or looseness ofthe 20* parts.

Figure 1 is a side elevation of a brake hanger bracket embodying myinvention. Figure 2 is a top plan View thereof, and Figure 3. is asectional view in the vertical plane substantially 251bisecting said jawas indicated by the line 3-3 of Figure 2.

' Describing the structure in more detail, the truck frame member 2 hasthe integrally formed brake hanger bracket 4 terminating in a jaw-30-like structure with the flaring top and bottom walls 6 and l and thesubstantially vertically arranged rib 8 joining said top wall 6 withsaid frame member 2. The said jaw structure has also the side walls land I2, the forward edges 35 01: which are of arcuate formation asindicated at l4, said lateral walls being relatively shallow and formingwith the before-mentioned flaring top and bottom walls the'pocket [6 atthe rear of said jaw. On the bottom wall I may be seated 40 my novelform of wear plate 18, said wear plate comprising a hook-shaped rearportion 20 having a configuration to seat against the forward edges M ofthe lateral walls of said jaw. Said hook-like member 20 provides a seatas at 22 for 45 the top member 24 of the loop-type brake hanger 26 ofwell known form. The forward portion of the wear plate 18 has clearanceat the top as indicated at 28 from the flat U-shaped spring 30, saidspring having a relatively long leg 3|, 50 the extreme inner end ofwhich has hearing as at 32 against the said top member 24of the'brakehanger, the other relatively short leg 33 of said U-shaped spring 30overlying thetop .jaw 6 and having a central opening 34 aligned withother 55: wopenings 36 and 38 in the forward .portions'of the top andbottom walls 6 and l of said jaw' structure and with the relativelylarge opening 35 in the bottom leg of said spring andthe opening 39 inthewear plate l8. Within said aligned openings maybe received thesecuring bolt 40 the head of which is seated on the top leg 33 0f theU-shaped spring 30 and the opposite .end of which receives the threadednuts 42, 42.

It will be apparent that after assembly of the parts,the U-shaped spring30 by the bearing at 32 upon the top member of the brake hanger willprevent vibration of that member and of the wear plate I8 upon which thehanger is seated. The bottom surface of the said wear plate it has aconfiguration complementary to that of the lower portion of the jawstructure and is seated thereupon. The retaining bolt 40 serves tosecure all of said parts in position but in addition thereto the wearplate l8 has along its bottom edges the lateral flanges 44, 44 whichoverlie the lateral edges of the bottom wall I, thus adding furtherstability.

It will be seen that my novel arrangement substantially closes the openend of the jaw struc- ,ture and affords compact and efiicientarrangement of parts so cooperating that the tension of the U-shapedspring is efiective to hold all parts in secure and tight relationshipwith one another after the retaining bolt has been secured in position.30

It is to be understood that I do not wish to be limited by the exactembodiment of the device shown which is merely by way of illustrationand not limitation as various and other forms of the device will, ofcourse, be apparent to those .35 skilled in the art without departingfrom the spirit of the invention or the scope of the claims.
